A site in southern California, containing 50,000 cubic yards of petroleum contaminated soil, was remediated using land treatment. By using a combination of soil screening and land treatment, the total petroleum hydrocarbon content was reduced to less than the clean-up standard of 1,000 mg/kg. Initial contaminant concentrations ranged between 4,000 and 5,000 mg/kg after screening to remove large globules of tar and pieces of asphalt. Biological treatment time was less than eight months. Simple parametric and nonparametric statistical methods were applied to the results obtained from soil testing. Multiple analytical methods were used to determine the type of residual hydrocarbon and the relative environmental risk associated with the residual contamination. This combination of physical segregation. land treatment, and statistical and analytical methods resulted in soil remediation and permission to use the soil on site without restriction.
